Weiler 85826 4" Nylox Disc Brush, Rectangular Filament, 80Sc Fill, 7/8" Arbor Hole - Manufactured using a tufted filament configuration and longer trim length for increased aggression, greater conformability and longer product life in comparison to monofilament disc brushes, which feature a distribution of short individual bristles. Abrasive brush filaments are manufactured by extruding a mixture of liquefied polymer and abrasive grain. Unlike the filaments used in DIY grade abrasive brushes, industrial grade products like Weiler? s Nylox and Burr-Rx brushes feature the highest grade of abrasive filament manufactured using a Type 6.12 nylon polymer.
Industrial grade filaments also feature the highest quality abrasive materials that have been sifted and sorted to ensure that the grains are consistent in size. Silicon Carbide is a sharp-edged grain that produces an effective cutting action. It is the most common grain used in industrial grade brushes. Made in USA
